"So why Roxy?" Penelope asked Luke while they were in the elevator with Luke's dog.
"I like that name for a dog, I thought it would be cute."
"Oh, well next time you talk about someone or something, specify if they are human or not."
Luke laughed at her. He started to grow feelings for her, but he couldn't do anything because she had a boyfriend. He couldn't help but smile every time he looked at her. She was so confident in herself and her looks.
"So what are you doing tonight, hanging with your clarinet playing boyfriend?"
She scoffed at his remark.
"He doesn't play it, he just helps me. And no I'm not hanging out with him tonight, we kinda broke up."
"Kinda, what does kinda mean?"
"It means that he wasn't interested in me anymore and decided to sleep around with other girls." Penelope said as she looked down at her shoes.
Luke looked at her face and could tell that she was on the verge of crying. So he made a bold decision and decided to hug her.
He put his arms around her and rubbed her back, and he could hear her sniffling from a runny nose caused by the tears.
Roxy tried nudging her way between them to get a hug too.
Penelope laughed and let go of Luke and bent down to give Roxy a hug.
"She seems to like you." Luke said as he watched the girl he liked give his dog a bear hug.
"Well I like her too. I had a dog that looked like her when I was little."
"Hey." Luke said trying to get Penelope to look up at him, while bending down to look her in the face.
She turned her attention away from Roxy and looked at Luke.
"He's a jerk for doing that to you."
Penelope opened her mouth to say something, but the elevator doors opened up to the parking garage, they stood up and walked out.
He was parked in the front lot, so they walked to his car so he could put Roxy in the back.
"So since you're not doing anything, do you wanna go and get a drink?"
"I told you I don't drink on a school night, remember. Besides I wouldn't have a way to get home without driving myself, and I don't drink and drive."
"Alright, well how about tomorrow. It's a Friday and if you can't drive yourself home we can catch a taxi or an uber."
Penelope didn't know what to say, they guy who she had grown to both loath and like at the same time was asking her out.
"Uhm, sure."
"Great, your not going to regret it. See you tomorrow."

It was two months later.
Penelope and Luke did go out for drinks that Friday, and it ended up lasting through the night at his place.
They didn't plan of going back to his place, but when Luke offered Penelope couldn't refuse his charm.
They stayed up all that night talking, and by the time the clock hit 3 am, Luke had his lips pressed against Penelope's.
They decided to not tell the team about their new relationship, they didn't want to deal with the drama of being a BAU couple.

Penelope had been staying the night at Luke's place a lot lately, she even had some of her clothes hanging in his closet. She was sitting at his kitchen table filling out some paperwork that the head chief of FBI needed.
She was just about done when Luke walked into the kitchen.
"Hey, watcha doin." He said as he walked into the kitchen and kissed her forehead.
She looked at him and smiled before continuing with the paperwork.
"I'm just finishing up some paperwork for work. I really wish that I didn't have to do work stuff when I wasn't at work."
He couldn't help but smile at her.
"Well when you are done, I was thinking that we order a movie."
"Deal, but as long as it's not a scary movie, you know how much I hate scary movies."
"I promise no scary movies, we can watch a comedy, as long as I get to hold you while we watch it." He said as he took her hands into his and pulled her onto his lap.
She giggled as he wrapped his strong arms around her and kissed her neck.
She looked at him and pressed her lips onto his.
"Now can I please finish the paperwork, and then I'm all yours." She said as she slowly moved her hand down to his pants and unbuttoned them.
He let out a small growl as she did that.
"Forget the paperwork." He said as he picked her up bridal style and carried her to the bedroom.
He laid her down on the bed and left a trail of soft kisses from her neck to her lips.
"You're all mine now."
She giggled at him.
He pulled his pants off as she took off her shirt.
He quickly climbed on top of her and started kissing her with all the passion inside of him.
Penelope let out a small moan, which made Luke smile.
He started to pull down her sweat pants when all of a sudden her phone went off. They both signed at the interruption.
Pen picked up her phone that was on the bedside table and let out a groan. The message was from Emily, letting her know that they had a case.
"Looks like we have a case."
Luke took her phone from her hands and tossed it across the bed.
"They can wait 10 minutes."
Penelope giggled and pulled him down to kiss her.
He wrapped his arms around her waist and finished pulling her sweat pants down.
He kissed her neck and she got tingles got her spine.
Never had Penelope been so comfortable with a man, Luke was everything she ever wanted in a guy, and it helped that he was handsome too.

They took separate cars to the BAU, they didn't want anyone to suspect anything.
Penelope arrived about 5 minutes before him and headed straight for the round table.
She walked in and saw everyone waiting for her, well everyone except Luke.
"Hey, you made it." JJ said laughing at her.
"I had just gotten out the shower when I got your text, so it took me a little while longer. Shall I get started?"
"Let's wait for Alvez to get here, he should be here soon." Said Reid as he looked through the case file on his table.
Just then Luke walked in.
"Ok, let's get started." Emily said as she sat down in her seat.
